Designing of thiocarbamide based CuI catalysts and their application in synthesis of 1,2,3-triazole based N,N-bis-sulfonylated and N-alkyl-N-sulfonylated G1 dendrimers have been reported. The designed catalysts showed the better catalytic activity under liquid assisted grinding (LAG) using 0.05 - 0.06 mole percent. Yield of dendrimers was observed from good to excellent in short reaction time period.

Solid Solution Rods: Though mono-metal oxides exposed special facets can be easily prepared via various approaches, the synthesis of mixed metal oxides exposed special facets are still a challenge to date. In this work, Sn−Mn mixed oxide nano-rods exposed (110) facet have been successfully synthesized by a facile one step hydrothermal method for the first time and showed superior CO catalytic oxidation performance.

In our work, we report a kind of tiny hollow nano-Co3O4 decorated 3D graphene aerogels (3DG) in the first time, which derived from direct oxidation carbon wrapped Co/3DG through Kirkendall effect. Due to its unique structure, the hollow Co3O4/3DG shows excellent ORR catalytic activity with almost four-electron reduction pathway.

With this report, a three-component cascade reaction encompassing in situ synthesis of Pd NPs supported on mpg-C3N4, dehydrogenation of AB and the transfer hydrogenation of nitroarenes were achieved in a commercially available pressure tube at room temperature within only 1–2 min. Besides the tandem reactions, the mpg-C3N4/Pd catalyst was isolated from the reaction medium to be tested as catalyst in the hydrolytic dehydrogenation of AB.

Amine-functionalized SBA-15 act as effective Pd2+ scavenger and as-generated surface bound Pd0 NPs are found to be highly active heterogeneous catalyst for base-free transfer hydrogenation of styrene to ethylbenzene using formic acid as an environmentally benign hydrogen source. The optimized reaction protocol for styrene also yielded excellent results for various substituted styrene and other alkenes. The role of free propylamine is found to be very crucial for higher conversion and selectivity of the desired alkane products.

In the context of valorization of biomass waste water containing polyols, it is reported that graphene in the absence of any metal catalyzes the decomposition of ethylene glycol into hydrogen and carbon dioxide due to the presence of hydrogenating/dehydrogenating sites. Control experiments have shown that the presence of acid or bases influences the activity of graphene as catalyst, while the reaction is not influenced by the presence of radical quenchers

The goal of this research was to understand the mechanism of AsO33− and F− removal using the chitosan (CS) reinforced ZrxAl1-xOOH material. A detailed batch experimental study was performed to understand the nature of the interactions that exist between CS@ZrxAl1-xOOH and F−/AsO33− in aqueous solution. The developed material is environmentally benign as it offers several advantages like simple way of preparation, quick and high uptake capacities, cost effective with the added benefit of recyclability.

The electrochemical reaction mechanism for Bi1-xBaxF3-x (x=0, 0.1, 0.2, and 0.4) electrode materials, which have several crystal structure types such as orthorhombic, hexagonal, and cubic was investigated. Regardless of the crystal structure in the pristine state, the crystal structure changes into the hexagonal phase after one cycle, which is the most reactive structure type of the three phases.

The Crystallographic studies of pyrazolone derivative linked with pthalimido through oxapolymethylene linker have been carried out for conformational study. The influences of folded and open conformation depend upon oxaploymethylene linker but no effect of substitution (methyl and benzene) on pyrazolone ring. The compounds 5 and 6 had shown folded conformation linked through oxaethylene spacer but compounds 7 had shown open conformation linked through oxapropylene linkers. However, DFT calculation revealed that all molecules have shown folded conformation. Further, the intermolecular interactions that stabilized crystal packing have been studied through pixel calculation and Hirshfeld surface analysis.

A condensation of ambident electrophilic &#x3B2;-chlorovinyl aldehydes with guanidines was developed for the synthesis of a library of 4- and 5-substituted 2-aminopyrimidines derivatives under mild conditions by employing potassium carbonate in methanol.

Pyridinium and imidazolium ionic liquids with perfluorinated side chains and different anions were prepared and the wettabilities of the materials were investigated by water contact angle measurements. The compounds were investigated in an effort to develop perfluorinated compounds for textile impregnation as alternatives for environmentally persistent commonly used perfluoroalkyl carboxylic and sulfonic acids.

Computational and crystallographic studies of the C7H6X2 (X = Cl, Br) system shed light on its ambivalent structure: In the solid state, the compounds exist as ionic halotropylium halides, whereas in solution, there is a highly dynamic equilibrium between different covalent isomers via their ionic form.

Easy and efficient separation of byproducts can be carried out in tin-mediated radical reactions by using stannyl reagents anchored to vinylic addition polynorbornene (VA-PNB). Advantageously, the stannyl polymers can be reused.

Rearranged cage ketones have been prepared in eight linear synthetic steps from 2,5-dimethoxybenzaldehyde without the use of protecting groups. The Diels–Alder reaction, [2+2]photocycloaddition, and Lewis acid promoted rearrangement with BF3·OEt2 were the key steps. This rearrangement approach opens up a new synthetic strategy to prepare interesting and unusual cage molecules.
